Marco Rubio, a freshman Senator from Florida, has endorsed Mitt Romney. The Tea Party favorite was elected in 2010 and has been floated as a possible vice president pick. Republicans have long seen Marco Rubio as the key to the Hispanic vote, however a Fox News poll shows 14% of Hispanics would vote for Mitt Romney, as compared to 70% for President Obama. Many Republican analysts say that they need at least 40% of the Hispanic vote in order to win.
